Box 2009 <br /> Stockton, CA 95201 <br /> PROPOSAL FOR REMEDIATION SERVICES, MOnIL SERVICE STATION, 2315 TRACY <br /> BOULEVARD, TRACY, SAN JOAQUIN COUNTY <br /> We have reviewed both the 14 April 1989 Proposal for Remediation Services <br /> prepared by Hart Cr=er, Inc. and the case file for this site. Our comments <br /> are as follows: <br /> 1 . The work outlined in Task I of this proposal is acceptable to us for a <br /> Wil investigation. <br /> 2. This work plan was not signed by a Civil Engineer, Geologist, or <br /> Engineering Geologist registered by the State of California. Mobil <br /> should be reminded that the actual work is to be conducted under the <br /> supervision of a California Registered Civil Engineer, Registered <br /> Geologist, or Certified Engineering Geologist. <br /> 3. The soil sample to be collected near the waste oil tank should be <br /> analyzed for all the waste oil constituents listed in Table 42 of the <br /> Tri-Regional Recommendations. <br /> 4. Following COMpletion of the work 00tKned in Task 1 , additional <br /> monitoring wells will be required to define the extent of ground water <br /> contamination. A work plan for the well installations should be <br /> developed and submi0ed to our agencies along with the results of the <br /> work performed in Task 1 . ibis site has had known ground water <br /> contamination since August 1986 and the extent of the plume has yet t,� <br /> be defined. We believe that the work necessary to obtain the required <br /> information to develop a complete and comprehensive Problem Assessment <br /> Report (PAR) should be conducted as soon as possible, <br /> 5. On the site map thyro is an area labaled "Area to be Excavated" . it was <br /> not referred to in the work plan, and there is no soil data to show that <br /> this area has contaminated soil . The extent of soil contamination <br /> should he defined and reported prior to Proposing remedial action , <br /> If you have any questions, Wase call me at (516) 361-5725. <br /> EDWAN JAMES ' <br /> Eng i n, F I LE <br /> FWJ:ewj <br />
